I noticed that Tesla has snow chains for sale in their accessory store. I'm snow-chain ignorant. Can snow chains be used in place of regular snow tires in the event of a big snow? I'm specifically thinking of instances in Chicago Where we get a big snow and I have trouble getting out of the alley, which is never plowed. The city's great plowing all of these main streets and expressways. I'm just wondering how the temporary use of the chains would work.
